    Subject2.5.62-mjb3 (scalability / NUMA patchset)
    The patchset contains mainly scalability and NUMA stuff, and anything 
    else that stops things from irritating me. It's meant to be pretty stable,
    not so much a testing ground for new stuff.

    I'd be very interested in feedback from anyone willing to test on any
    platform, however large or small.


    Since 2.5.62-mjb2 (~ = changed, + = added, - = dropped)

    Notes: Fixes some critical scheduler hangs.

    + fix_was_sched Ingo / wli / Rick Lindsley
    + no_kirq Martin J. Bligh
